Werner Horvath calls his style "New Constructivism" after the philosophical theory, based on the works of Vico, Uexkull, Glasersfeld, Watzlawick and others. The theoretical background is explained in detail by the artist in a stage play in form of a text-collage, called "Jahrtausendwende - Die Theorie des neuen bildenden Konstruktivismus" (in German). Horvath tries to show in his paintings, that the so-called reality is not so "real" at all, for the world we live in can be understood as constructed by ourselves. For instance, colors do not really exist, but are products of the visual system and therefore are only "real" within our consciousness. But also forms of all kind have no reality outside our subjective world; on the contrary they are built up by several psychological mechanisms. And at last we have to take into consideration, that we live in a "symbolic world": We see Stalin not only as a politician who lived from 1879 to 1953, but also as a symbol of dictatorship and cruelty.
As precursors of his style Horvath names Giuseppe Arcimboldo and M.C.Escher. Most of Horvath's paintings are influenced by political events or deal with political problems.
